Clearly, some creative thinking is badly needed if humans are to have a future beyond Earth. Returning to the Moon may be worthy and attainable, but it fails to capture the public's imagination. What does get people excited is the prospect of a mission to Mars.

I can get very philosophical and ask the questions Keats was asking as a young guy. What are we here for? What's a soul? What's it all about? What is thinking about, imagination?

I've got an overactive brain. I enjoy work, I enjoy life, and I'm not good at relaxing. I've also never slept very much due to this overactive imagination and my brain constantly thinking.

The conscious process is reflected in the imagination; the unconscious process is expressed as karma, the generation of actions divorced from thinking and alienated from feeling.

Today mythical thinking has fallen into disrepute; we often dismiss it as irrational and self-indulgent. But the imagination is also the faculty that has enabled scientists to bring new knowledge to light and to invent technology that has made us immeasurably more effective.

My mom would always read a book to me at night from when I was three. Now, I can't go to sleep without reading a book. At the same time, once I read, it's difficult for me to go to sleep, as I have an overactive imagination and I start thinking.

The capacity you're thinking of is imagination; without it there can be no understanding, indeed no fiction.

Learning a musical instrument is challenging, it demands fine motor skills and coordination. It develops children's listening, thinking skills, imagination and perseverance. It brings out the very best in the children as they work collaboratively with their peers and teachers.

The use of travelling is to regulate imagination by reality, and instead of thinking how things may be, to see them as they are.

Good acting is thinking in front of the camera. I just do that and apply a sense of humor to it. You have to trust the audience to get it.

I remember seeing McCoy Tyner in concert, and thinking that the music was incredible, but wanting to be invited in. I figured that humor was the way of letting the audience in. I've gotten a hard time about it, but I love to be funny onstage.

So, I'm thinking of a name for a villain that has a sense of humor. I thought of 'The Joker' as a name, and as soon as I thought that, I associate it with the playing card, as my family had a tradition of champion playing; my brother was a contract champion bridge player. There were always cards around the house.

Anyone in the humor business isn't thinking clearly if he doesn't surround himself with idea people. Otherwise, you settle for mediocrity - or you burn yourself out.

You do see more people that have been freed up over the last couple of hundred years to do work that is more about thinking about or creating things... and I would hope to see that trend continue.

As a young actor, people were trying to define who I was before I really knew that for myself. But I still remember thinking, 'This is what I love doing, and I hope I'm going to be able to do it forever.'

I had to stop going to auditions thinking, 'Oh, I hope they like me.' I had to go in thinking I was the answer to their problem.

If you keep thinking about what you want to do or what you hope will happen, you don't do it, and it won't happen.

I knew I was a winner back in the late sixties. I knew I was destined for great things. People will say that kind of thinking is totally immodest. I agree. Modesty is not a word that applies to me in any way - I hope it never will.

I totally expect there to be some young girl or boy sat at home thinking 'I want to be like Kadeena Cox,' and then going on to better everything I've done.

The killer app that got the world ready for appliances was the light bulb. So the light bulb is what wired the world. And they weren't thinking about appliances when they wired the world. They were really thinking about - they weren't putting electricity into the home. They were putting lighting into the home.

Buy with your heart, not your head. You can look at all the aspects that make a purchase practical, but that kind of thinking makes it an investment rather than a home.

I work day-to-day on C# and .Net and work at home two days a week so I can do deep thinking, writing and reflecting.

I used to do my best thinking while staring out airplane windows. The seat-back video system put a stop to that. Now I sit and watch old' Friends' and 'Everybody Loves Raymond' episodes. Walking is good, but here again, technology has interfered. I like to listen to iTunes while I walk home. I guess I don't think anymore.

My life at home gives me absolute joy. There are some days when, as soon as you've finished cooking breakfast and cleaning up the kitchen, it's time to start lunch, and by the time you've done that, you're doing dinner and thinking, 'There has to be a menu we can order from.'
